New Build Keyboard Doesn't Work in BIOS

Like to thank everyone that contributed to my post from a month ago. My problem ended up being the front power button has a few tiny wires that plug into a small plastic block. I always thought this was some kind of ground. Turns out this small block is supposed to be plugged into the MB which is how the power button, HD lights et al get juice. In fact, I think this small block somehow got unplugged from my old MB which would mean I didn't need a new MB all this time. Oh well.

I have an old, standard USB keyboard and a PS/2 mouse plugged into the back of my PC. I hit DEL on startup so as to get into BIOS and make it point on startup to my DVD drive. The Sabertooth MB I use has a real nice "Windows" looking BIOS program, I hit DEL and get to the main BIOS page but that's it. Keyboard and mouse don't work.

So I guess the question is I finally got my PC build functioning. What is the first thing YOU would do to get this rig up and running??? Weird cause I've been building my own rig for about 15 years. Every five years I drop about $1500 in parts so I can get the latest and the greatest. 5 years seems to be about the time it takes for most standards to change. USB 2.0 into 3.0. SATA 3 into SATA 6. Vid cards are much stronger, more stable. Thanks for the help.
 
Make sure your mouse and keyboard are plugged into usb 2.0 ports and not 3.0 ports as they won't work until you get inside windows.
 
Thanks. Yes they are plugged into 2.0 and the keys work cause I hit DEL on startup and it gets me to the BIOS main screen but after that, keys/mouse don't work.

Do I need to load drivers? Seems the MB is already loaded with what it needs to run Windows. The discs they send are just back up, yes?
 
Has the keyboard ever worked in the bios? Does the computer have a ps/2 port to see if you can try a ps/2 keyboard?
 
Like I said in my first post, PS/2 mouse is plugged in and the keys are plugged into USB 2.0. When the UEFI BIOS main page shows up (after pressing DEL on startup) I have no control over either keys or mouse. Anyone ever in the situation before? Keys/mouse don't work in UEFI BIOS?

I have no HDs plugged in and only my DVD drive is plugged in. Ideas?
 
My wireless Bluetooth keyboard worked flawlessly for years in everything including BIOS. I have that and an old USB keyboard and a PS/2 mouse. My Bluetooth keyboard has all the mouse functions built in which I love.

When I plug in the USB keys and the PS/2 mouse.....on powerup it recognizes the keys when I press the DEL key but that's it.

Question.....my Sabertooth MB is already preloaded with everything it needs to install and run Windows.....yes? The DVDs they send are just in case something bad happens and I lose the MB drivers.....yes?? I don't have to load any MB drivers do I once I get the MB up and running??? I can't remember ever having to do that with any of my old builds but I could be wrong.

Play this out like this is your rig. It's all up and running so what do you do next....exactly.
 
Do you know what version of bios this motherboard is running? Could be a bios update issue.
 
I do believe thats the latest bios verison. So I'm at a loss here at what could be the problem.

If you could possibly find a ps/2 keyboard and test it. You can at least confirm if its a usb port issue, although I know you said your ps/2 mouse doesn't work either. You don't need the motherboard cd to get things to work in bios, it should just work. You can try resetting the cmos or using the jumper to do it. Just looks like this is a board issue.
 
Do you get the same behavior with the PS/2 mouse disconnected?

The only other thing I can think of is that it's trying to use the wrong device over PS/2. You should be able to use KB shortcuts from within the BIOS menu, or if you had a spare USB mouse laying around I'd give that a go and remove the PS/2 one.
 
Most new boards come with USB keyboard and mouse support enabled. Try resetting the bios or find a old PS/2 keyboard and see if it works in the bios and enable it.
 
Thanks guys. You have no idea how this thing has me crying at night.

I have to download shit to my cell and cast it to my chromecast to watch any tv. EEEEeeeeeeeeeeee..........
